/* * The struct perf_event_attr test support. * * This test is embedded inside into perf directly and is governed * by the PERF_TEST_ATTR environment variable and hook inside * sys_perf_event_open function. * * The general idea is to store 'struct perf_event_attr' details for * each event created within single perf command. Each event details * are stored into separate text file. Once perf command is finished * these files can be checked for values we expect for command. * * Besides 'struct perf_event_attr' values we also store 'fd' and * 'group_fd' values to allow checking for groups created. * * This all is triggered by setting PERF_TEST_ATTR environment variable. * It must contain name of existing directory with access and write * permissions. All the event text files are stored there. */ #include #include #include #include #include "../perf.h" #include "util.h" #include #include "tests.h" #define ENV "PERF_TEST_ATTR" extern int verbose; static char *dir; void test_attr__init(void) { dir = getenv(ENV); test_attr__enabled = (dir != NULL); } #define BUFSIZE 1024 #define __WRITE_ASS(str, fmt, data) \ do { \ char buf[BUFSIZE]; \ size_t size; \ \ size = snprintf(buf, BUFSIZE, #str "=%"fmt "\n", data); \ if (1 != fwrite(buf, size, 1, file)) { \ perror("test attr - failed to write event file"); \ fclose(file); \ return -1; \ } \ \ } while (0) #define WRITE_ASS(field, fmt) __WRITE_ASS(field, fmt, attr->field) static int store_event(struct perf_event_attr *attr, pid_t pid, int cpu, int fd, int group_fd, unsigned long flags) { FILE *file; char path[PATH_MAX]; snprintf(path, PATH_MAX, "%s/event-%d-%llu-%d", dir, attr->type, attr->config, fd); file = fopen(path, "w+"); if (!file) { perror("test attr - failed to open event file"); return -1; } if (fprintf(file, "[event-%d-%llu-%d]\n", attr->type, attr->config, fd) < 0) { perror("test attr - failed to write event file"); fclose(file); return -1; } /* syscall arguments */ __WRITE_ASS(fd, "d", fd); __WRITE_ASS(group_fd, "d", group_fd); __WRITE_ASS(cpu, "d", cpu); __WRITE_ASS(pid, "d", pid); __WRITE_ASS(flags, "lu", flags); /* struct perf_event_attr */ WRITE_ASS(type, PRIu32); WRITE_ASS(size, PRIu32); WRITE_ASS(config, "llu"); WRITE_ASS(sample_period, "llu"); WRITE_ASS(sample_type, "llu"); WRITE_ASS(read_format, "llu"); WRITE_ASS(disabled, "d"); WRITE_ASS(inherit, "d"); WRITE_ASS(pinned, "d"); WRITE_ASS(exclusive, "d"); WRITE_ASS(exclude_user, "d"); WRITE_ASS(exclude_kernel, "d"); WRITE_ASS(exclude_hv, "d"); WRITE_ASS(exclude_idle, "d"); WRITE_ASS(mmap, "d"); WRITE_ASS(comm, "d"); WRITE_ASS(freq, "d"); WRITE_ASS(inherit_stat, "d"); WRITE_ASS(enable_on_exec, "d"); WRITE_ASS(task, "d"); WRITE_ASS(watermark, "d"); WRITE_ASS(precise_ip, "d"); WRITE_ASS(mmap_data, "d"); WRITE_ASS(sample_id_all, "d"); WRITE_ASS(exclude_host, "d"); WRITE_ASS(exclude_guest, "d"); WRITE_ASS(exclude_callchain_kernel, "d"); WRITE_ASS(exclude_callchain_user, "d"); WRITE_ASS(wakeup_events, PRIu32); WRITE_ASS(bp_type, PRIu32); WRITE_ASS(config1, "llu"); WRITE_ASS(config2, "llu"); WRITE_ASS(branch_sample_type, "llu"); WRITE_ASS(sample_regs_user, "llu"); WRITE_ASS(sample_stack_user, PRIu32); fclose(file); return 0; } void test_attr__open(struct perf_event_attr *attr, pid_t pid, int cpu, int fd, int group_fd, unsigned long flags) { int errno_saved = errno; if (store_event(attr, pid, cpu, fd, group_fd, flags)) die("test attr FAILED"); errno = errno_saved; } static int run_dir(const char *d, const char *perf) { char v[] = "-vvvvv"; int vcnt = min(verbose, (int) sizeof(v) - 1); char cmd[3*PATH_MAX]; if (verbose) vcnt++; snprintf(cmd, 3*PATH_MAX, PYTHON " %s/attr.py -d %s/attr/ -p %s %.*s", d, d, perf, vcnt, v); return system(cmd); } int test__attr(int subtest __maybe_unused) { struct stat st; char path_perf[PATH_MAX]; char path_dir[PATH_MAX]; /* First try developement tree tests. */ if (!lstat("./tests", &st)) return run_dir("./tests", "./perf"); /* Then installed path. */ snprintf(path_dir, PATH_MAX, "%s/tests", get_argv_exec_path()); snprintf(path_perf, PATH_MAX, "%s/perf", BINDIR); if (!lstat(path_dir, &st) && !lstat(path_perf, &st)) return run_dir(path_dir, path_perf); return TEST_SKIP; } /table>

sh_eth: rename EESIPR bits
Since the commit b0ca2a21f769 ("sh_eth: Add support of SH7763 to sh_eth") the *enum* declaring the EESIPR bits (interrupt mask) went out of sync with the *enum* declaring the EESR bits (interrupt status) WRT bit naming and formatting. I'd like to restore the consistency by using EESIPR as the bit name prefix, renaming the *enum* to EESIPR_BIT, and (finally) renaming the bits according to the available Renesas SH77{34|63} manuals; additionally, reconstruct couple names using the EESR bit declaration above...
